If a party is supporting a country committing genocide along ethnic lines because of the very ethnicity that’s in control in that country and would not do it if a different ethnicity was dominant, then they’re at the very least extremely racist, “racist” because their support is based on ethnicity “extremely” because not even Genocide along ethnic lines makes them waver in their support.
In the Modern Era (post WWII) extreme racism is a far-right trait.
It looks at lot like in Germany most of the political landscape has not evolved away from seeing people and nations as etnics first and foremost, which is one of the core foundations of Fascist thinking, including Nazism.
Outside the Racist, Fascist logic, “never again” is about such things not being done to any people not merely to people of a specific ethnicity.
Even the non-Fascist Right would only ever rationalise support of a country committing genocide along ethical lines on money terms (just look at most of the US’ support for dictatorships) or security terms (I.e. “they’re valuable allies”) rather than ethnic composition of the government and population of the country.
It was actually a major disappointment for me to discover that German political thing hasn’t actually moved all that much away from some Nazi principles about the worth of human beings.
